Article graphic analysis, dividing the convolution face in the direction of a rolling plane in the direction of the cutting board, the thickness of the rolling area on the left of the normal line is thinner and the unrolling area on the right side of the normal line is thicker; similar to the plane rolling method, the unrolling area is thinner in the normal contact area, and the material is moving forward according to the constant volume condition. Extension, so as to reach the purpose of rolling. Because the convolution rolling method has many advantages, such as multi level rolling and multi cycle, its rolling efficiency is greatly improved.
